What makes the world go round Photosynthesis

Photosynthesis is the process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities. Photosynthesis is largely responsible for both producing and maintaining the oxygen content of the earth and supplying the organic compounds and energy necessary for life on earth.

The first step is the light dependent reaction. In this step, energy from the sun is collected by the chlorophyll and converted for use by the plant.

Next, H2O is split and an electron is sent through photosystem 2. The spliting of H2O releases oxygen. Here, it gets energized. As the electron travels, it loses energy. Because of this, the electron enters photosystem 1 to be re-energized. After that, it then keeps traveling and makes NADPH and ATP.

After the light dependent reaction comes the Calvin cycle, where carbon is sent through six times to make energy and sugars for the plant.

The carbon goes around and makes ADP and NHDP+. These molecules can go back in the thylakoid to help with the light dependent reaction. It also creates G3P and rubisco. The G3P is sent out to make glucose and rubisco. Rubisco then is used to make RuBP, which is the starting point of the Calvin Cycle.

Through this process, carbohydrates are made. These carbohydrates are used to make sugar which sustains the plant. Oxygen is also created as a byproduct.
